Anritsu's VectorStar Vector Network Analyzer

VectorStar features a completely new platform that utilizes a new innovative architecture. It offers a new performance benchmark for S-parameter measurements of RF, microwave and millimeter-wave devices, allowing for the broadest frequency sweep from a single coaxial test port in a single instrument, covering 70 kHz to 70 GHz. For applications from 70 kHz to 2.5 GHz, a mixer-based receiver with bridges for directional devices is used. Above 2.5GHz, a harmonic-sampling receiver is incorporated, with the traditional couplers for directional devices. Since the couplers are not taxed by extending to low frequencies, available power is not traded for frequency coverage, resulting in superior dynamic range. VectorStar now provides RF and microwave engineers a powerful measurement tool for performance analysis of devices ranging from transistors in an on-wafer environment to communication systems in commercial/defense applications. Unlike other analyzers where speed compromises accuracy and trace noise, the VectorStar's unique design architecture minimizes trace noise by using a more coherent Source/LO pair. The result is ultra-low trace noise without having to increase IF filtering, which slows the sweep speed. Speed is not limited to just the display. Users can quickly download data to your external database while moving on to the next device to maximize throughput. With a starting frequency as low as 70 kHz and a stop frequency of 20, 40, 50 and 70 GHz, VectorStar provides the broadest frequency coverage available. VectorStar can also address the needs of the ultra broadband community with the capability of spanning from 70 kHz to 110 GHz in a single coax connector.
